BLANK-BOOK.

SPECIFICATION forming part of Letters Patent No. 407,886, dated July 30, 1889.

Application filed March 25, 1889. Serial No. 304,743. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT A. W. WINZEN- BURG, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Blank-Books; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to no make and use the same, reference being bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The invention relates to that class of blank- 15. books in which the leaves are sewed to stubs,

and after being particularly described inconnection with the drawings will be pointed out in the claim.

Figure 1 of the drawings is a perspective view of the blank -book with the sections spread apart; Fig. 2, a rear view thereof, and Fig. 3 a detail perspective view of the stub.

In the drawings, A represents the stubs, each folded at a a a so as to answer the pur- 2 5 pose intended. To the fold a of each stub is sewed a section B of the leaves of the blankbook, and into this fold fits one turned end a of the stub, the edge covering the threads of the stitch. The stub end a is by means of the fold (1 brought between two layers of the nextstub, and at the folds a the stubs are sewed together. The stub or guard A is made of any light fabricsuch as canvas or muslinand with strips C of paper, as shown in Fig. 3 of the drawings.

It will be observed that the first part of the second stub is inserted underneath and in the last of the preceding stub and the two there sewed together, and so on until all the stubs are fastened in place.

It will be seen that by my invention the endof one stub is sewed to one end of another and around the bands D on the back of the book; hence each stub is twice sewed in one sewing. On opening the book the threads which fasten the stubs are invisible.

Having thus described all that is necessary to a full understanding of my invention,what I claim as new, and desire to protect by Letters Patent, is

A blank-book having the stubs A folded at a a a sewed to sections of the blank leaves at folds a and to one another at folds (R, as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.-

ROBERT A. WV. WINZENBURG.
